I'm actually pretty happy with the Tesla system, and it DOES ask you to hold the wheel in sharp turns, faded lane markings, etc. It complains loudly if you ignore it. It's miles from full autonomy, of course, but for what it does it works quite well in my experience driving between Seattle and Whistler, BC in snow, rain, and heavy wind twice in the last month (I only received the autopilot update a few weeks ago). It has clear limits and it's quite aware of them in general, protectively requiring drivers to take over before it runs up against them.
